The boy’s body was found on Feb. 26, 1999, in a wooded area by a small church cemetery along Clifton Springs Road in DeKalb County, Georgia.

Investigators believe the body was placed in its resting place carefully before they found it three to six months later.

“The most disturbing thing is, we … haven’t connected an actual reported missing or death to this child,” said DeKalb County Medical Examiner Director Patrick Bailey, according to a video from the National Center for Missing & Exploited Children.

To date, investigators still don’t know the child’s name or how he died.

The medical examiner said he wasn’t malnourished or poorly-cared for. He was, by all accounts, your average 4- to 8-year-old boy.

The one thing that set him apart was that his clothes suggested he had “above the average means for most income levels,” the medical examiner said.
